My Flavor of choice is BBLean, because I can drag and drop wallpapers to my desktop. Now I'm sure those of you who have tried running Blackbox from your USB or tested it without installing noticed there were some minor features you couldn't use without installing(or so you first thought). Ditto. Like how some icons never show up in the tray, I have a shortcut for you.
1.Three finger Salute Ctr+Alt+Del , This brings up task manager
2. Kill the Process Tree for Explorer.exe
3. From the task manager, start a new task:
[path-to-blackbox]\Blackbox.exe
4. Presto, you're running Blackbox without installing and your BlackBox tray now loads all icons.
With this you can have BBLean running portable.
